AS"IGNOR TO LVE-IITIN A. CGRPORATON OF DETACHING MOTGN COMBNG MACHINES.

Application filed July 19, 1922,

To all whom t may cof/cera Be it known that l, SIGURD Hermann,

a citizen of the United States, residing in VVhitinsville, Massachusetts, have invented the following described lmprovements in Detaching Motions for Combing Machines.

The invention consists in the relative arrangement and general organization of the gearing of the detaching mechanism of Heilman type coinbers, as hereinafter more fully disclosed, adapting such mechanism for construction in compact, durable and efficient form so as to be applicable to existing combers within the space available in these compact machines and adapted also to produce various kinds of piecing roll movement according to the ratios of the gears einployed.

ln the accompanying drawings: Figure l is a transverse section of part of the drive head of an ordinary cotton comber using this invention, with parts brok-en out and shown in section, and Figure 2 is a side elevation.

These figures will be sufficient to illustrate the principles of the invention and their relation to other usual parts of cotton combers, not shown in the drawing. lt will be understood that the drive pulley l, through the pinion 2 and gear 3 drives the main or comb cylinder shaft d and that a number of comb cylinders 5 are ordinarily mounted on such shaft, one for each combing head; also that the lap to be combed is appropriately fed to and through the nipper mechanism anl held by the latter so that its forward end is combed by the comb cylinder and thereafter presented to or grasped by the detaching rolls 7 (Fig. 2) by which the combed end of the lap is detached from the lap, as a tuft, and drawn through the top comb, and then pieced in over-lapping relation to the previously detached tuft to form the combed sliver. The particular detail of the combing cycle however, is of no consequence to thisinvention because the principles of the latter are applicable to the drive of detaching and piecing rolls of various types of combers as above stated and as will hereafter become apparent. ln the machine taken for illustration, there are two detaching and pissing-roll shafts 7 which,

itl

Serial NO. 575,922.

in multiple head combers will be understood to entend through the machine so as to serve all the heads thereof. rllhese shafts are provided with two equal sized gears 8 and 9, situated close together in offset positions within the drive head compartment, and close to the frame upright l0, which separates the drive head space from the next adljacent combing head. These gears are connected by a superposed wide faced idler 1l journaled on a stud l2 carried by the said frame upright so that both roll shafts are thus connected to rotate in like direction and at like angular speed. The wide faced idler ll is formed in one piece or compounded with the gear i8 which is the gear by which both det-aching rolls are driven in this particular machine. rlhis arrangement is well known and it will also be understood that where the combing machin-e employs but a single detaching roll shaft the idler ll is omitted and the pinion on the end of said shaft then serves the same function as gear 13. Such a pinion or gear 13, as the case may be is driven from the drive-pinion 2 by the organization of parts embodying and representing thisinvention and such organization includes a short lay shaft la journaled at one end in the aforesaid frame upright l0 and at its other end in a bracket l5. This shaft is equipped. with a crank 16 oscillated by the connecting rod of an eccentric?? carried ou the main cam shaft i8 of the comber, which latter shaft commonly eX- tends through the length of the comber, as will be understood. #l ny other shaft avail able in the comber might be employed for oscillating the crank i6, but the existing cani shaft lSis utilized for this purpose, in the present case, because it makes one revolution for each nip and because is desirable for the purpose of the invention that the said crank be oscillated by a crank rather than a cam motion.

rlhe lay shaft 14 also carries, fixed upon it, one of the side gears 19 of a diderential or epicyclic gear set and carries, rotatable upon it, the sleeve 2O of the spider member of that set. This spider member comprises the said sleeve 2Q and an apertured web 2l and is provided with lateral side walls or shrouds 22 and 23 which, with the other members of the set, form an enclosure for the planetary pinions and all the intermeshing gear teeth of the set. The opposite side gear 24, which is the driven member of the epicyclic gear set, is formed on a sleeve hub rotatably journaled on the sleeve 20 of the spider member and also formed in one piece with, or connected to a larger gear 25 which meshes with and drives the gear 13 above referred to- The shrouds 22 and 23 of the spider member carry the journal pins 26 of the planetary pinions, which are also compound gears, each consisting of gear members QT and Q8. For convenience of manufacture one of the shrouds 23, is a separate ring appropriately secured to the rim of the spider member, but obviously both shrouds can be integral with the spider member if desired. Their inner margins are fitted concentrically to the offset webs of the two concentric side gears 1,9 and 24, and preferably by means of a rebate or staggered joint as shown in the drawings.l The webs of both gears are imperforate so that the enclosure formed by the spider member and the gears is adapted to be filled with and to retain lubricant. The gears may thus run in mass of oil. The side shnouds and the gear webs preferably occupy the same planes which are close together as apparent from the drawing. rlhe box form spider carries an external circumferential set of gear teeth 29 and its diameter and the shaft 1st are so proportioned. and placed with relation to the comb shaft and detach-ing rolls, that these teeth may mesh directly with a drive pinion 30 secured to the comb cylinder shaft 4. By this connection the box form spider is driven continuously in the direction of the arrow in Fig. 1. During this continuous and constant speed rotary movement the eccentric 17 imparts one complete oscillation to the crank 16 and side gear 19 for each revolution of the comb cylinder shaft, the result being that the compound side gear 2li-25 receives aprogressing oscillation of greater extent in one direction than in the other, and this motion is transmitted to the detaching rolls, through the gearing 13 already described, causing them to rotate forwardly a certain amount and then backwardly a less amount, on each nip and as required for machines of the Heilman type. It willbe seen that the extent, aswell as the angularl velocity of the detaching roll movement is controlled by the relative size of the gears and that in particular the velocity of the movement is controlled by the proportions of the gears-of the epicyclic set and the length of the oscillating crank 16. These relations will be generally apparent from the drawings and as shown are suitable to give a proper piecing motion when operated by an eccentric or crank motion, as distinguished from cam actuation,

and may give a substantially constant velocity to the detaching rolls when rotating forwardly, and this velocity may be so nearly constant as to adapt one of the detaching rolls to nip the cotton against a detaching half lap on the cylinder, when the invention is applied to combers of that class. The oscillated driving gear 19 is preferably larger than the driven gear 24 and each successive couple in the gear set multiplies the velocity and this relation is combined with a crank radius which is longer than either side gear thereby adapting the mechanism to run quietly and smoothly with the least deterioration and development of lost motion as the result of wear.
